_____________________ involves inheritance of one characteristic and contrasting traits controlled by a gene.

• dihybrid inheritance

• monohybrid inheritance

• self cross

• purebreed

A ______________is the basic unit of

inheritance which consists of a DNA segment located on a specific locus of a chromosome.

• allele

• trait

• gene

• phenotype

_______________ is an allele

which always shows its trait when it is present, and suppresses the effect of recessive allele.

• recessive trait

• dominant trait

• recessive allele

• dominant allele

_________________ is an allele which shows its trait when

both alleles are recessive allele

• recessive trait

• dominant trait

• recessive allele

• dominant allele

__________________ is expressed when both alleles are dominant alleles or one dominant allele is paired with a recessive allele.

• recessive trait

• dominant trait

• recessive allele

• dominant allele

_________________ is expressed if a recessive allele is paired with another recessive allele.

• recessive trait

• dominant trait

• recessive allele

• dominant allele

Recessive trait is expressed if a recessive allele is paired with another recessive allele is known as

• phenotype

• genotype

• heterozygote

• homozygote
